Tele2 partners with Nokia Siemens Networks to enhance its European fiber optic backbone

(07 giu 2007) - Nokia Siemens Networks work with Swedish Tele2 to build a new pan-European Dense Wavelength Division Multiplexing (DWDM) network that can support 40 Gigabits per second and wavelength on every link. The new network will bolster Tele2’s fast-growing IP backbone network, and link major European telecommunications nodes. The new core transport network will enable Tele2 to cost-efficiently offer its customers new IP services and enhance its transmission capacity.

The Tele2 project relies on the SURPASS hiT 7300, an optical platform that allows the realization of metropolitan to ultra-long haul transport applications on a flexible DWDM network architecture. The main advantages of this new technology for Tele2 are increased service quality and flexibility, as well as reduced costs. The unique automation features of the platform enable hands-off provisioning of new services, resulting in Tele2 being able to effortlessly adjust its bandwidth as needed. The SURPASS hiT 7300 platform integrates technology from Stratalight Communications into its platform technology to support the 40Gbit/s transmission rates per wavelength.

Tele2’s new optical backbone will cover Central Europe. The deployment started in the second quarter of 2007.
Uwe Fischer, head of the DWDM business line at Nokia Siemens Networks, said: “The demanding transmission requirements of Tele2 make this project quite unique. It will show that SURPASS hiT 7300 is a powerful and flexible platform that can easily handle huge traffic flows.”

The SURPASS hiT 7300 is a flexible and cost-efficient 40-channel DWDM transport platform optimized for high-capacity transport, and ranges from 200 to 2,000 km links. It is designed and optimized for bit rates of 2.5, 10, and 40 Gigabits per second per wavelength. The comprehensive automation and customization of network configurations minimize system complexity, simplify network operation, administration and maintenance, and eliminate procedural errors, all contributing to lower CAPEX and OPEX.
